LS3 No OIL PSI I have a modded ls3, that just lost all oil pressure. It should be the check valve inside the oil pump. GM has a bulletin of some kind out for this problem. Putting in new Oil pump today. Just hope nothing got hurt inside the motor!!

Car is camed and procharged. Oil pump was not taken out prior. Did some investigating, and found that ls3 has some issues with check valve sticking open and not building pressure. Replaced with another stock piece that was worked over, and holds more oil psi.

Well I put 500 miles on it since the new oil pump, and everything seems to be ok. I did find that the procharger has a bad seal, and sent it off for repair. When everything gets put back together, track time will in it's future.
